Here's why you'll love it

The IsoSpeed rear decoupler equipped on the Domane SLR Gen 4 model, integrated cable routing, Kammtail tube aerodynamics, and our high-performance OCLV 800 Series carbon combine to create an ultralight, fast, and comfortable bike on the road.
RED AXS is SRAM's top-tier drivetrain, offering a fully wireless, super-light, precise, and ergonomic shift, while allowing you to brake with just one finger.
The IsoSpeed decoupler smooths out the road, while the generous tire clearance allows for up to 38mm tires, helping absorb the rough bumps of the road for a smoother, more comfortable ride.
The practical internal storage compartment provides a versatile solution for storing tools and gear, while the horizontal tube mounts allow you to attach a bag for carrying everything you need for longer adventures.
The crankset with integrated power meter makes it easy to monitor your power metrics.
